Sheldon: Hey, Stuart, have you read the new Flash?
Stuart: No.
Sheldon: Well I have and it will knock your socks off. Good luck getting them back on.

Sheldon: Just when I think I've gotten the hang of sarcasm.

Sheldon: This is nothing but a blatant abuse of power by a petty functionary. Explain to me why Wil Wheaton and his lackeys get in and we don't.
Movie Attendant: Because I'm the petty functionary with the clipboard, bitch.

Sheldon: (Playing hackey sack) One, two, three, four, five, six, seven, eight. Drat. I'm never going to get to forty-three again. One, two, three, four. Rats.

Sheldon: With the Xbox One I can control my entire entertainment system with voice commands. Up until now I've had to use Leonard.

Sheldon: Hold on, Dr. Leonard, where are your social skills? This man is clearly upset. We should invite him in for a hot beverage.
Leonard: He tried to score with Penny.
Sheldon: So have these two and they're having dinner with us.

Amy: Ooh, the Philharmonic is playing Beethoven down town.
Sheldon: Before you say yes, it's not the movie about the big dog.

Sheldon: Go, Amy Farrah Fowler. Follow your endocrine system.
Amy: Thank you, Sheldon. You are a good friend.

Sheldon: Penny, I'm a physicist. I have a working knowledge of the entire universe and everything it contains.
Penny: Who's Radiohead?
Sheldon: I have a working knowledge of the important things in the universe.

Sheldon: (On helium) Kripke! I found the nozzle. I'm gonna kill you!

Sheldon: I believe you were about to ask me to choose a cocktail. Fortunately, thanks to computer-savvy alcoholics, there's an app for that.

Leonard: Come on, there's four of us and one of him.
Sheldon: Which means his triumph will be even larger. Minstrels will write songs about him.

Sheldon: Yeah, I think you'll appreciate this, very exciting.
Dr. Gablehauser: Oh, what are you working on?
Sheldon: Something remarkable. Since my prospects for the Nobel Prize in physics have disappeared, thank you very much, I've decided to refocus my efforts and use my people skills to win the Nobel Peace Prize. Look, I'm going to solve the Middle-East Crisis by building an exact replica of Jerusalem in the middle of the Mexican desert.
Dr. Gablehauser: To what end?
Sheldon: You know, it's like the baseball movie, build it and they will come.
Dr. Gablehauser: Who will come?
Sheldon: The Jewish people.
Dr. Gablehauser: What if they don't come?
Sheldon: We'll make it nice, put out a spread.

Sheldon: (Mandarin) Long live concrete? Thank you.

Sheldon: Listen to what Mr. Wil Wheaton is tweeting: "Best seats in house for Raiders screening. Suck on that, Sheldon Cooper."
Leonard: Why do you read his Twitter feed? You know it's gonna upset you.
Sheldon: I believe in knowing my enemy, Leonard. Had Twitter existed at the time, would not General Custer have followed the tweets of Sitting Bull? Would not Lee have followed Grant? Would not Spy have followed Spy?
